I'm a real noob to Javascript/JSON, so this might be really obvious. I'm storing values to chrome.storage in a chrome extension JS file: 

chrome.storage.sync.set({'username' : username}, function() {
    console.log('Saved',username);
}); 
chrome.storage.sync.set({'password' : password}, function() {
    console.log('Saved', username);
});

I know it's passed correctly because the console.log returns the right values.

Then I try to retrieve it in my content script, but it only returns [object Object]. 

chrome.storage.sync.get("username", function (username) {
    console.log("Passed successfully: Username "+username);
    studentUsername = username;
});

chrome.storage.sync.get('password', function (password) {
    console.log("Passed successfully: Password "+password);
    studentUsername = username;
});

I'm not sure why it's doing this.

Yes, it always returns an object. You'll have to access the property from the object.

chrome.storage.sync.get("username", function (obj) {  
    console.log("Passed successfully: Username "+obj.username)
    studentUsername = obj.username; 
});
